Amongst the various things found useful in keeping birds, I may mention, first, the cages, varying from the cheapest and commonest forms to the largest and most elaborate aviaries - these have been herein described.

A tray for placing all the apparatus on.

A few tin canisters, or glass preserve-jars, or even common bottles, without corks, for containing the seeds ; "without corks," because of the danger of small pieces being swallowed by the birds ; glass stoppers may be used.

A bread-grater is essential; and if there are many birds, a small marble mortar will be serviceable, for rubbing down hard-boiled eggs. A coffee-mill will be useful, because easier to work than a mortar.

A glass dish for a bath; with a wire basket, for suspending it in the aviary.

A sieve, for sifting the seed or sand from the husks or dirt, will be wanted.

A piece of hard wood, twelve inches square, made on the principle of what housekeepers call a chopping-board; that is, having a back to it, and a low strip or wall on each side. On this place your hemp-seed, to crush it with a hard rolling-pin. After using it, scrape and scald the board.

A spatula, or apothecary's knife, and a glass spoon, both of which must be kept sweet and clean.

To cleanse the floor of an aviary by removing the sand, a hoe will be needed. A trowel also, for scraping the corners of the floor.

The sand should be coarse, or rather gravel.

Of course, you will keep well supplied with sponges, flannels, nail-brushes, seed glasses, to replace broken ones.
